m.PAD Phase and Feeder Identification for Live LV
by MADE-SA
Identifies Phase & Feeder
Runs Live
Simple to Use
Clear Display
Signals via Feeders
No Radio Problems
m.PAD is used to determine or confirm
customer connections on an LV network.
The transmitter is connected by croc clips
(or banana plugs) to each phase and neutral
voltage at any point in the sub-station, and is
powered from phase 1 & 2 for continuous
operation. In addition, up to 12 Rogowski coils
are each closed around all 3 phases of outgoing
feeders.
The hand-held receiver has two voltage
probes, or a mains plug, and when these are
placed in contact with the phase and neutral at a
customer connection it draws a specific current
signal which is detected by the transmitter, which
in return sends the phase and feeder identification
to be displayed on the receiver. The
communication technology used is unique to
MADE-SA and assures error-free indication.
The system is CE marked and
manufactured to NF EN 50065-1, 50082-1,
(EMC) & 61010 Electrical Security.

OPERATION
The transmitter is connected and turned on in the substation, with the Rogowski coils in the
correct orientation. The transmitter display gives setting up information and, in use, shows
the network frequency and phase rotation; Once the receiver has been used, the transmitter
shows the most recent Feeder and Phase identification, and the time since it was made.
Making a Measurement.
The receiver is connected between phase and neutral (this is very important, otherwise the
system will not start and the overvoltage LED will light), the receiver is automatically
powered-up, the green LED lights, and the message « Reception … » is shown. It then
behaves as a « special » load detected by the transmitter.
Check that the operation is correct by the « signal » LED. This lights briefly approximately
each four seconds.
Wait for the display to show the result in the form « Dxx Lx », for example « D05 L2 » for
feeder N°5, phase N°2. The same conventions are adopted in the case of ambiguity of the
feeder (D??) and feeder not identified (D--) as for the transmitter.
Even if the feeder is not identified, the phase may be identified. However the inverse is not
possible in principle.
Once disconnected from the mains the receiver maintains the display for several seconds
before shutting off. It is then possible to consult the result again by pressing the ON
button, the receiver is turned back on (supplied by the internal battery), but the green LED
remains unlit. Only the last result can be displayed.
When the receiver is reconnected to the network, the previous result is effaced by reinitialisation of the system so that there is no doubt about the source of the result
displayed;
If the ambient lighting is too low, pressing the left-hand button starts the backlighting. A
second press turns off the backlighting.
mPAD also verifies the phase rotation of the network, clockwise or anticlockwise.
The system has a self-test mode with an associated wiring loom so that its correct functioning
can be confirmed in the field.
